Budgeting
You can add, hide and delete the units of a budget.
In an account, **Unit** says what the **Quantity** counts, such as days, weeks or a flat fee. For all accounts and subaccounts of a budget, you choose from the same list of units. To change the list, you need a budget you can edit.
In the budget, open the list in an account's **Unit** cell and choose **Edit**. KOSMA opens **Units**. You can open **Units** only from a **Unit** cell.
Click  **Unit**. KOSMA adds a row named **New Unit** at the end of the list and places the cursor in its name. Type the name of the unit.
A name can appear only once in the list. If another unit already has the name, KOSMA shows:
Name must be unique
To hide a unit, click  in its row. KOSMA then shows the unit faded. The unit stays in the list, and every account that uses it keeps it. To show the unit again, click .
**In Use** shows how often the unit is used. To delete a unit, click  in its row. KOSMA opens **Delete Unit**. If no account uses the unit, KOSMA asks:
Are you sure you want to remove unit {name}?
Click **Ok** to delete the unit.
If accounts use the unit, KOSMA lists them below this message:
Are you sure you want to remove unit {name}? Deleting it will clear the unit from the entries below. You can delete anyway.
With **Delete anyway**, every account in the list loses its unit. Its **Unit** cell is then empty.
Click **Delete anyway** to delete the unit, or **Cancel** to keep it. [Why some things can't be deleted](/kb/article/why-some-things-cant-be-deleted) explains the other dialogs KOSMA shows when you delete something.
Click **Ok** to close **Units**.
**If the controls in Units are greyed out.** You cannot edit this budget. KOSMA greys out the controls on a **Free** licence (also after your trial has ended), on a budget shared with you for reading only, on a budget linked to a cost control set, and when you are not signed in. To see the reason, point at  **Unit**. [What your licence includes](/kb/article/what-your-licence-includes) lists what each licence lets you edit.
